Abstract

The invention discloses a seawater temperature profile rapid measurement system and measurement method based on an unmanned aerial vehicle. The system comprises an unmanned aerial vehicle platform, aload rejection mechanism installed on the belly of the unmanned aerial vehicle, an airborne disposable temperature profile measurement instrument and a remote control center arranged on a shore base or a ship base. The unmanned aerial vehicle platform is used for flying to a designated sea area to put the airborne disposable temperature profile measurement instrument, and is further used for receiving seawater temperature profile measurement data and sending the seawater temperature profile measurement data to the remote control center; the load rejection mechanism is used for mounting and throwing the airborne disposable temperature profile measuring instrument; the airborne disposable temperature profile measurement instrument is used for measuring a seawater temperature profile after being thrown into water and sending the seawater temperature profile measurement data to the unmanned aerial vehicle platform; and the remote control center is used for controlling the unmanned aerial vehicle platform to fly and further used for receiving the seawater temperature profile measurement data remotely sent back by the unmanned aerial vehicle platform. The timeliness and efficiency of seawater temperature profile parameter measurement of a target sea area are improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of marine hydrological element measurement, in particular to a rapid measurement system and method for seawater temperature profiles based on an unmanned aerial vehicle. Background technique [0002] Seawater temperature profile data is one of the most basic marine environmental elements and a physical quantity that reflects the thermal status of seawater. The distribution of the seawater temperature profile and its change with time directly affect the propagation speed and path of sound waves in the ocean. The rapid acquisition of seawater temperature profile data can provide important assistance for marine scientific research. [0003] The Disposable Temperature Profiler (XBT) is a disposable measuring device that senses and measures the seawater temperature profile during its rapid descent by dropping a single-use XBT probe. [0004] At present, the launching of XBT probes is generally done by ships sailing to th...
